JOSEPH O. FARLEY, OF N ORTH YAKIMA, WASHINGTON.

PUMP.

Application filed October 20, 1915.

To all whom it may concern Be it known that I, JosErH O. FARLEY, a. citizen of the United States, residing at North Yakima, in the county of Yakima and State of Washington, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved pump and has for its primary object to provide a very simple and durably constructed force pump provided with automatically operating valves.

The invention has for a more specific object to provide in a pump of the above type, an oscillating paddle or blade arranged between the opposed intake ports, oscillating valves alternately opened in the movement of the blade whereby the fiuid is drawn into the pump case, said case having an outlet, and additional oscillating valves arranged upon opposite sides of the shaft of said blade and preventing the back flow of the water which is forced into said outlet.

The invention has for a further object to generally improve and simplify the construction of pumps and provide simple and reliable means, the several elements of which are compactly assembled in a pump of relatively large capacity.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which,

Figure 1 is a vertical section of a pump illustrating one embodiment of my invention; Fig. 2 is a'section taken on the line 2-2 of Fig. 1, the oscillating blade being partially broken away; Fig. 3 is an enlarged fragmentary perspective view of the oscillating blade; Fig. at is a section taken on the line l& of Fig. 3; and Fig. 5 is a detail elevation showing an alternative means for operating the oscillating blade;

Referring in detail to the drawings, 5 designates the body of the pump having the water receiving chamber 6. The opposed side walls 7 of this chamber converge upwardly while the base wall thereof is concavely curved, as at 8. At the opposite ends of this curved base wall of the water receiving chamber, the pump body is provided with intake ports 9 towhich pipes or other Specification of Letters Patent.

7 thereof,

Patented Nov. 21, 1916.

Serial No. 56,974.

Water supply connections, indicated at 10, are suitably secured.

In the top wall of each of the intake ports 9, the journal 11 of an oscillating valve plate 12 is mounted for rocking movement. In the present embodiment of my invention, I have shown the pump in Fig. 2 provided with a pair of intake ports 9 on each side, and a common valve plate 12 for each pair of ports. To the marginal edges of each of the valve plates 12 and on each face of the plate, packing strips, indicated at 13, are secured by means of the metal binding strips 1 1. At each end of the concave base wall 8 of the water receiving chamber, a transversely disposed, vertically inclined shoulder 15 is formed in the bottom wall of the chamber, against which the free longitudinal edge of the oscillating valve plate 12 normally rests. One end of each of the valve plates 12 is movable in a triangularshaped recess or pocket 16 formed in one of the end walls of the pump. The opposite end wall of the pump is provided with an opening 17 of similar shape, which is adapted to be closed by a removable plate 18 securely bolted to the end wall of the pump body over said opening. The opposite end of the oscillating valve plate 12 is movable in this opening 17. The valve plates 12 may be readily removed through the openings 17 in the side wall of the pump case.

Above the convergently inclined side walls 5 of the pump body, a cylindrical bearing 19 integrally connects the opposed end walls thereof. In this bearing, the shaft 20 of the oscillating paddle or blade 21 is journaled- A central division wall or web 22 projects upwardly from the bearing 19 and divides the head portion of the pump body into separate outlet ports 23 which dischargeinto a common receiving pipe 24 fixed to the pump head.

25 designates the rock shafts or journals of a pair of oscillating valve plates which are mounted in the side walls of the pump body and on each side of the central bearing 19. This bearing is provided upon its periphery, at diametrically opposite points with longitudinally extending shoulders 26 upon which the free longitudinal edges of the valve plates 27 normally seat and close communication between the water receiving chamber 6 and, the outlet ports 23.

Exteriorly of the pump case, an arm 28 is fixed to one end of the shaft 20. In a suitable support 29, secured to one side of the pump body, a pair of shafts, indicated at 30 and 31, are mounted and have their axes disposed in the same vertical line. A belt wheel 32 is fixed upon the shaft 30 and is driven by a belt from any suitable source of power. A pinion 33 is also fixed upon the shaft 30 and meshes with a large gear wheel 34 on the shaft 31. A rod 35 is eccentrically connected to the wheel 3 at one of its ends and has its other end pivotally connected to the arm 28.

In the operation of my improved pump as above described, it will be understood that, in the rotation of the wheel 3%, the paddle or plate 21 is oscillated in the water chamber of the pump case. IVhen the blade moves to the left, to the position shown in Fig. 1, the right hand oscillating valve plate 12 is drawn by suction to its open position and water is drawn into the chamber 6. In the reverse movement of the blade 21, this right hand valve plate 12 closes and the water is forced upwardly past the right hand valve plate 27 and through one of theoutlet ports 23 into the receiving pipe 24. At the same time, the left hand valve 12 is opened and water is drawn into the chamber 6 on the left hand side of the blade 21. When the movement of the blade is again reversed, the water is forced upwardly and the left hand valve plate 27 moved to its open position so that the water passes through the outlet port 23 into the receiving pipe 24. In this manner, it will be understood that water may be quickly pumped in large quantities. As the arrangement of the valves and their construction is exceedingly simple and entirely automatic in operation, the several parts of the pump will not get out of order or require frequent repairs. The marginal edges of the valve plates 27 are provided with packing strips in a similar manner to the intake valves 12 above described. The marginal edges of the oscillating blade 21 also have packing strips 36 secured thereto on the opposite faces of the blade by means of the metal binding strips 37, as clearly shown in Figs. 3 and 1 of the drawings. These marginal packing strips effectually prevent leakage of the water from one side of the valve plates or the pump blade around the edges thereof to the opposite side of the valve plates or blade.

In Fig. 5 of the drawings, I have shown an alternative means for operating the oscillating pump blade, wherein the rock shaft 20 of the pump blade is provided upon its end with an arm or bar 38 extending in opposite directions and radially with respect thereto, and to the extremities of this arm, the cables or ropes 39 are connected which may be alternately wound and unwound upon drums or operated by any other suitable means.

From the foregoing description, taken in connection with the accompanying drawings, it is believed that the construction, manner of operation and several advantages of my invention will be clearly and fully understood. It will be appreciated that I have produced a pump which is powerful in its action and capable of pumping large volumes of water in a comparatively short length of time. It is, of course, apparent that the pump may be constructed with a water receiving chamber of any desired capacity and provided with a requisite number of intake and outlet ports. The device is also susceptible of many other modifications in the form, proportion and arrangement of the several elements employed and it will, therefore, be understood that I reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is a In a pump, a case having a water receiving chamber and intake ports at opposite sides thereof, laterally swinging valve plates fulcrumed in the case above said intake ports, the side wall of the case being provided with openings through which said valve plates may be readily inserted or removed, said valve plates operating at one of their ends in said openings, plates secured to the pump case and closing said openings, said valve plates moving by gravity to their closed positions, an oscillating pump blade mounted to operate in said chamber, the pump case having spaced outlet ports above the fulcrum of the oscillating blade, and oscillating valve plates normally closing said outlet ports.

In testimony whereof I hereunto afix my signature in the presence of two witnesses.
